metatheria การใช้

• In their comment, PlatinumX, cited two reasons for switching from Marsupialia to Metatheria.
• The therians are further divided into the marsupial Metatheria and the " placental " Eutheria.
• Evolutionary relationships among genera of Phalangeridae ( Metatheria : Diprotodontia ) inferred from mitochondrial data.
• Huxley's Prototheria-Metatheria-Eutheria is almost a renaming of the older system.
• A variant of the Prototheria-Metatheria-Eutheria system is the Prototheria-Theria system.
• Firstly, the article on the taxon " Metatheria " seems to suggest it is the more modern taxon.
• Secondly, University of Michigan Museum of Biology uses " Metatheria " rather than " Marsupialia ".
• The Prototheria-Metatheria-Eutheria system has a number of miniscule differences from the Monotremata-Marsupialia-Placentalia system.
• Logically, under the Prototheria-Theria scheme, the infraclass of Prototheria corresponding to Eutheria and Metatheria should also be called Prototheria.
• Eutheria means'true beasts', reflecting a feeling that placentals were'superior'in the evolutionary line over Prototheria and Metatheria.
• Within mammalia, "'TMEM239 "'orthologs are found in organisms belonging to eutheria and metatheria, but not prototheria.
• Metatheria can be roughly translated as'intermediary beasts', referring to a common belief at that time that marsupials were ancestors of placentals.
• Huxley s system, in which The three subclasses are Prototheria, Metatheria, and Eutheria, rather than Monotremata, Marsupialia, and Placentalia.
• ""'Arcantiodelphys " "'is an extinct genus of basal Metatheria which existed in France during the Cenomanian age.
• "' Metatheria "'is a mammalian clade that includes all mammals more closely related to marsupials than to placentals ( such as sparassodontans ).
• Within Metatheria, a 2016 phylogenetic analysis group found that borhyaenids form a clade with the Asian " Gurlin Tsav skull " as well as other South American taxa.
• The marsupials constitute the crown group of the Metatheria, and include all living metatherians as well as many extinct ones; the placentals are the crown group of the Eutheria.
• In some classifications, extant mammals are divided into two subclasses : the Prototheria, that is, the order Monotremata; and the Theria, or the infraclasses Metatheria and Eutheria.
• The threefold division of living mammals into monotremes, marsupials and placentals was already well established when Thomas Huxley proposed the names Metatheria and Eutheria to incorporate the two latter groups in 1880.
• In that case, Holotheria has become synonymous with Theriiformes, as there are no other groups in that subclass, so that my Cladotheria-Metatheria-Eutheria system could be used.
